Polymer Composites for Civil and Structural Engineering
Synthetic polymers and fibre reinforced polymer composite systems have
become increasingly important to the civil and structural engineer over the
last decade and now have a wide range of applications in a variety of
engineering fields.
A large percentage of all fibre reinforced products are made from unsaturated
polyester resins reinforced with glass fibre. However, epoxy and
toughened epoxy resins and the high technology thermoplastic polymers,
together with the carbon and aramid fibres, are playing an ever more
important role in structural engineering, particularly in the aerospace
industry, but increasingly in the construction field, and this trend is likely
to continue, as chapter 1 convincingly demonstrates. Polymer composites
have unique advantages over more conventional materials and these
advantages can be enhanced by correct design technology; the engineer has
the opportunity to design the composite material and the structural system
simultaneously.
An attempt has been made to combine, within one book, information on
the various composite systems currently in use in construction, together with
fabrication processes, mechanical and physical properties of the matrices,
fibres and composites, analytical and experimental testing and design
techniques and jointing methods. The section on failure theories is a generic
presentation in that structural composites generally consist of various
multi-ply laminates which will fail when subjected to a sufficiently large load.
It will be realized that the failure of composites is complicated because of
the many different ways in which structural systems can collapse. Therefore,
this section can serve only as a guide to the prediction of structural integrity.
The aims of this book, therefore, are to provide a simple guide to the
principal aspects of the theory and use of composites in construction. It is
directed at consulting engineers and designers of polymer composites in the
mechanical and civil engineering industries, but will also serve as a reference
source for advanced undergraduates and postgraduates studying materials,
and material scientists interested in the utilization of composites in
engineering.
